That option is currently not used by any defconfig and could not be set
anymore since it became mandatory to used Kconfig when introducing new
options with U-Boot v2016.11 or commit eed921d923 ("Kconfig: Add a
whitelist of ad-hoc CONFIG options") and commit 371244cb19 ("Makefile:
Give a build error if ad-hoc CONFIG options are added").
It was also not considered when fixing build warnings in
commit 39ac34473f ("cmd_mtdparts: use 64 bits for flash size,
partition size & offset") and could probably not be compiled anyway
after commit dfe64e2c89 ("mtd: resync with Linux-3.7.1"), which
renamed some members of struct mtd_info … so it was probably broken
since then, which was U-Boot v2013.07-rc1.

This declaration is not used anywhere in the whole tree. There is a
function 'mtd_id_parse()' which was renamed from 'id_parse()' in
commit 68d7d65100 ("Separate mtdparts command from jffs2"), but that
function is not used (anymore?) in cmd nand and build is fine without
that declaration, so it's probably just safe to remove.

When full malloc is enabled and SYS_MALLOC_F is also enabled, the simple
pre-reloc heap is used before relocation. In this case, calloc() uses
the MALLOC_ZERO macro to zero out the allocated memory. However, since
this macro is specially crafted for the dlmalloc implementation, it
does not always work for simple malloc.
For example, when allocating 16 bytes via simple malloc, only the first
12 bytes get zeroed out. The last 4 bytes will remain untouched.
This is a problem for DM drivers that are allocated before relocation:
memory allocated via 'platdata_auto_alloc_size' might not be set to
zero, resulting in bogus behaviour.
To fix this, use 'memset' instead of 'MALLOC_ZERO' to zero out memory
that compes from simple malloc.

The default implementation of ERR_PTR/PTR_ERR maps errno values at the
and of the address range (e.g. -EINVAL/-22 gets 0xFFFFFFEA).
For socfpga gen5 SPL, this doesn't really work, as the heap is nearly
at the end of the 32 bit address range.
This patch adjusts the ERR_PTR_OFFSET to map errno values into the range
of the Boot ROM, which should not be used for valid pointers.

This patch changes ERR_PTR/PTR_ERR to use CONFIG_ERR_PTR_OFFSET to map

Some U-Boot pointers have redundant information, so we can use a scheme
where we can return either an error code or a pointer with the same
return value. The default implementation just casts the pointer to a
number, however, this may fail on platforms where the end of the address
range is used for valid pointers (e.g. 0xffffff00 is a valid heap pointer
in socfpga SPL). For such platforms, this value provides an upper range
of those error pointer values - up to 'MAX_ERRNO' bytes below this value
must be unused/invalid addresses.
